On-line adsorption/preconcentration using a knotted reactor for total Hg determination in drinking water by flow injection CV-AAS

An on-line mercury pre-concentration and analysis system using atomic absorption spectrometry (AAS) and flow injection (FI) with cold vapor (CV) generation was studied. The mercury was retained as a mercury-2-(5-bromo-2-pyridylazo)-5-diethplaminophenol [Hg(II)-(5-Br-PADAP)] complex, at pH 9.2. The m...
